I have an AGU and an AGN head sitting aroud right now, I'm gonna use both on the engines I'm building.
The AGU has the big ports you generaly describe as the AEB coded Heads and the AGN has the small ports....
Looking at both of them, I see the the ports are quite simillar inside (near the valves) and the sizes reduces a lot on the intake manifold flange.
By the first measurements I've taken, I can tell de small ported head CAN BE ported as the big port one, although the castings are a bit different and the big prted head has much more material.
I could Say that the small port heads CAN BE ported till the same flow as an AEB.
And the AEB's have just more material, tha could allow even more flow, witch I think isn't nescessary.
I'm going to measure them and take some pics to post here, but I'd like to know if somebody ever tried to port a small port head to be simillar to an AEB.
And, by the way, I'm in Brazil, so some engine codes might be a bit different.

but ended up going with a AEB that was then ported out for max flow.
